Let's divide 819637 by 20
We want to divide 819637 by 20.

Advancing to step 1:
8 divided by 20 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 20

On to step 2:
81 divided by 20 is 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 80 from 81 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 20

On to step 3:
20 goes into 19 0 times with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
If we take 0 away from 19, we end up with 19.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 20

Advancing to step 4:
20 can be fit into 196 9 times, resulting in a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 409.0
Subtract 180 from 196 to get 16.
Fetch the next digit (3) from the dividend, attach it to 16 and continue: 163 / 20

On to step 5:
If we divide 163 by 20, we get 8 and a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 4098.0
Deduct 160 from 163 and we're left with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 20

Advancing to step 6:
If we divide 37 by 20, we get 1 and a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 40981.0
Deduct 20 from 37 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 7:
When dividing 170 by 20, we get 8 with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 40981.8
If we subtract 160 from 170, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 40981.85
If we take 100 away from 100, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 40981.85
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 40981.85
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 40981.85 and a remainder of 0.0.
